A woman in the manβs culture of engineering education
The study is aimed at identifying barriers to the research career of women in the academic environment of a technical university. The authors present the results of their study of the womenβs status in the academic community. The study is based on a quantitative (questionnaire survey) and qualitative (biographical interviews) analysis of the opinions of students and teachers of STEM disciplines of a technical university about the features and problems of womenβs professional careers. It is established that women of the same university evaluate the presence and degree of influence of barriers to the research careers differently. In some cases, women assessing their professional status note that they do not feel professional discrimination on the basis of gender. In general, the analysis revealed that women who received a STEM education use a strategy of avoiding a research career and choosing alternative career options: either outside the academic environment, or by transitioning to teaching as a way to circumvent gender barriers in grant and publication activities.

.The article presents an analysis of the concept of Β«organizational cultureΒ» through the prism of a phenomenon of culture and different approaches to organizational culture are crystallizes. Culture is defined as historically certain level of society development and man, that expressed in the types and forms of human life organization, and material and spiritual values, which created by them. It is shown that one of the classifications of culture divided it into three types: monoactive (or linearly arranged), poliactive and reactive. Each of these types is characterized by a particular style of the information collection that defines the possibility of decisions making management when using this classification in organizations. The features of the interpretation of the concept of Β«organizational cultureΒ» are defined. The essence of the organizational culture is a set of values, which are the guidelines of behavior of employees, management decision-making guidelines, as well as a system of symbols and rituals that serve as a set of rules approved behavior of employees in an organization. Marked constituent elements of organizational culture: system of values, leadership style, the characters of organization, ceremonies and rituals, cultural organizationβs network. The main characteristics of organizational culture are: universality, informality, stability. It is shown that the components of organizational culture changing in the conditions of globalization, which calls for new forms and methods of work with personnel in modern organizations.Π ΡΡΠ°ΡΡΠ΅ ΠΏΡΠ΅Π΄ΡΡΠ°Π²Π»Π΅Π½Ρ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΡ Π°Π½Π°Π»ΠΈΠ·Π° ΠΏΠΎΠ½ΡΡΠΈΡ Β«ΠΎΡΠ³Π°Π½ΠΈΠ·Π°ΡΠΈΠΎΠ½Π½Π°Ρ ΠΊΡΠ»ΡΡΡΡΠ°Β» ΡΠΊΠ²ΠΎΠ·Ρ ΠΏΡΠΈΠ·ΠΌΡ ΡΠ΅Π½ΠΎΠΌΠ΅Π½Π° ΠΊΡΠ»ΡΡΡΡΡ ΠΈ ΡΠ°Π·Π»ΠΈΡΠ½ΡΡ

Dynamics of Vortex Pair in Radial Flow
The problem of vortex pair motion in two-dimensional plane radial flow is
solved. Under certain conditions for flow parameters, the vortex pair can
reverse its motion within a bounded region. The vortex-pair translational
velocity decreases or increases after passing through the source/sink region,
depending on whether the flow is diverging or converging, respectively. The
rotational motion of two corotating vortexes in a quiescent environment
transforms into motion along a logarithmic spiral in the presence of radial
flow. The problem may have applications in astrophysics and geophysics.Comment: 13 pages, 9 figure

A Dipole Vortex Model of Obscuring Tori in Active Galaxy Nuclei
The torus concept as an essential structural component of active galactic
nuclei (AGN) is generally accepted. Here, the situation is discussed when the
torus "twisting" by the radiation or wind transforms it into a dipole toroidal
vortex which in turn can be a source of matter replenishing the accretion disk.
Thus emerging instability which can be responsible for quasar radiation flares
accompanied by matter outbursts is also discussed. The "Matreshka" scheme for
an obscuring vortex torus structure capable of explaining the AGN variability
and evolution is proposed. The model parameters estimated numerically for the
luminosity close to the Eddington limit agree well with the observations.Comment: 17 pages, 11 figures, version of this paper is published in Astronomy

Gravitational potential of a homogeneous circular torus: new approach
The integral expression for gravitational potential of a homogeneous circular
torus composed of infinitely thin rings is obtained. Approximate expressions
for torus potential in the outer and inner regions are found. In the outer
region a torus potential is shown to be approximately equal to that of an
infinitely thin ring of the same mass; it is valid up to the surface of the
torus. It is shown in a first approximation, that the inner potential of the
torus (inside a torus body) is a quadratic function of coordinates. The method
of sewing together the inner and outer potentials is proposed. This method
provided a continuous approximate solution for the potential and its
derivatives, working throughout the region.Comment: 10 pages, 9 figures, 1 table; some misprints in formulae were
